IMPROVEMENT IN JOURNAL-BOXES.

Speciiication forming part of Letters Patent No. 212,665, dated February 25, 1879 application filedl January 14, 1879.

To all whom jt may concern:

Be it known that I, JEROME E. DEEEEEsT, of Troy, in the county of Rensselaer, and in the State of New York, have invented certain new and useful Improvements in Journal- Boxes; and do hereby declare that the followingis afull, clear, and exact description thereot, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The nature ot' my invention consists in the construction of a journal-box for railroad-car axles, engines, and other machinery, as will be hereinafter more fully set forth. v

In order to enable others skilled inthe art to which my invention appertains to make and use the saine, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a plan View of my journal-box. Fi 2 is a cross-section of the same on the line rv m, Fig. l. Fig. 3 is a longitudinal section thereof on the line y y, Fig. 1.

A represents the back ot"` the box, made of cast-steel, malleable or wrought iron, or any other suitable material. In the concave surface ot' this back are made transverse grooves a a and one or more longitudinal grooves, b, as shown. B represents the lining of the box, made ot' gun-metal, and provided on its convex surface with transverse and longitudinal ribs d c, to correspond with the grooves in the concave surface of the back. Between the back A and lining B is interposed a lead enshion, C, which is stamped or pressed to tit the grooves and ribs above described. The three parts A, B, and C are then securely fastened together by means of rivets h h, as shown.

The intermediate lead lining or cushion prevents heating, or the gun-metal lining B from breaking, and also renders the box noiseless.

The cleats or ribs and grooves prevent the gun-metal lining from moving either way.

This invention is applicable to both upper and lower bearings orjournal-boxes, tor railroad-car axles or journal-boxes for all kinds of machinery, engines, Src.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a journal-box, the combination of the back A, having grooves a b, the lining B, having ribs or cleats el e, and the intermediate lead cushion, C, the three parts being united by rivets, substantially as and for the purposes herein set forth.

In testimony that claim the foregoing I have hereunto set my hand this 7th day ot' J anuary, 1879.

JEROME E. DEFREEST.
